4.2.6.4.8Roaming Option (SU only)

The Roaming Option defines the roaming support of the unit. When roaming is not expected, it is preferable to set this parameter to Disable. This will cause the unit to start scanning for another AU after losing connectivity with the current AU only after 7 seconds during which no beacons were received from the current AU. This will prevent scanning for another AU in cases where no beacons were received due to a short temporary problem.

When set to Enable, the SU will wait only one second before it starts scanning for another AU. In addition, when the Roaming Option is enabled, the SU will send Roaming SNAP messages upon associating with a new AU. This enables fast distribution of the new location for all clients that are behind the SU. In this case, the SU will send multicast SNAP messages via the wireless link each time it associates with a new AU, except for the first association after reset. The SU will send one SNAP message for each client learned on its Ethernet port, based on its bridging table. In the SNAP message the clients’ MAC address is used as the source address. The AU that receives this SNAP message learns from it the new location of the clients. It forwards the SNAP to other AUs and Layer-2 networking equipment via its Ethernet port, to facilitate uninterrupted connectivity and correct routing of transmissions to these clients. The new AU as well as the previous AU with which the SU was associated, will forward the SNAP messages to all other SUs associated with them.

The default is Disable.

4.2.6.4.9Ports Control (SU only)

The Ports Control sub-menu includes the Ethernet Port Control option:

4.2.6.4.9.1 Ethernet Port Control

The Ethernet Port Control option allows enabling or disabling non-management traffic to/from the Ethernet port. When changed to Disable, all current data sessions will be terminated. The unit is still manageable via the Ethernet port even if it is disabled for data traffic.

The default selection is Enable.

4.2.6.4.10 Show Bridge Parameters

The Show Bridge Parameters option displays the current values of the Bridge parameters.
